HANDLE-FERRU'LE.

To all whom it may concern:

Be it known that I, EDWARD J. RENKEN- BERGER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Handle-Ferrules, of which the following is a specification.

This invention relates to improvements in the ferrules of tool handles, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

. Another object of the invention is to provide a simply constructed device of this character which readily adapts itself to and closely engages the handle regardless of its size or shape.

Another object of the invention is to provide a device of this character which will not become loosened by the shrinkage of the material of the handle.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and, in the drawings illustrative of the preferred embodiment of the invention, Figure l is a side elevation ofv the improved device; Fig. 2 is an end elevation; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 1 is a sectional detail on the line 1-4 of Fig. 2; Fig. 5' is a sectional detail,illustrating a modification in the mannerof securing the ferrule to the handle.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device may be applied to handles employed upon different kinds of tools, and to handles of different sizes and shapes, as the improved ferrule readily adapts itself to the handle regardless of its size or shape, and for the purpose of illustration the improved ferrule is shown applied to a conventional handle 10 for supporting a file, represented at 11, and inserted by its tapered tang 12 in the usual manner in a correspondingly tapered cavity in the handle.

The improved ferrule is formed from a single piece of wire first connected at one end to the handle by inserting its terminal therein and Winding around the handle upon the portion in which the tang is inserted and Specification of Letters Patent.

then fastening the other end of the wire by inserting the same into the material of the handle.

In applying the handle a strip of wire is employed and sharpened at its ends and one of thesharpened ends inserted into a cavity in the handle, as represented at 13, and thence extended for a short distance longitudinally of the handle, as shown at 14-, and toward the smaller end and inserted into a longitudinal recess. The body of the wire is then coiled tightly-around the handle, as shown at 15, and over the extension 1 1 and the terminal 13, as shown in Fig. 3, and carried any required distance toward the larger upper end of the handle and the other pointed terminal inserted into another cavity in the handle, as shown at 16, to secure the ferrule thus formed in position upon the handle.

Any suitable mechanism may be employed for winding the wire upon the handle, but as devices of this character are so well known it is not deemed necessary to illustrate them.

In the smaller end of the handle 10 a plurality of cavities or gains 17 are formed, as shown in Figs. 2 and 4, the gains being so disposed that the terminals 13 and 16 of the wire which compose the ferrule are located between two of the gains. The gains weaken the material of the handle so that when the tang 12 of the tool is forced into the cavity of the handle, if the material is inclined to split, the split will naturally occur where the gains are formed and will not therefore occur opposite the inturned ends 13 or 16. By this means no danger exists of weakening the hold of the ferrule on the handle by causing the material to split where the terminals are entered. This is an important feature of the improved device and adds materially to its efliciency and utility.

In Fig. 5 a slight modification in the manner of securing the inner end of the wire is shown, consisting in passing the inner terminal through a transverse cavity 18 and bending the terminal and forcing it into the material of the handle, as shown at 19. This latter means of securing the ferrule may be employed in certain kinds of handles that are subjected to severe strains and rough usage.

If required a drop of solder may be employed, indicated at 20, or at the point where the coils 15 first engage over the longitogether and also secure the ends of the ferrule in the recesses, cavities, or sockets in whlch they are embedded, so that displacement of the ferrule or of the coils of the 1 same will be prevented.

In Figs. 1 and 2 the handle is shown formed with a swell where the 00118 15 are placed, to produce a more convenlent and natural grip for the hand of the operator,

and it will be obvious that the handle may be given any required shape, as the coils will adapt themselves to any shape which maybe imparted to the handle. Generally the portion of the handle that is to be covered by the coils is reduced, as represented in Figs. 1 and 2, so that the general outer surface of the handle and the general outer surface of the coils will correspond and thus avoid any abrupt projections or enlargements, but produce a handle having a symmetrical and uniform outline.

- Any slze or form of wire may be employed and the wire may be plated or otherwise coated to increase the appearance and prevent corrosion.

j Having thus described my invention, what is claimed as new is:

1. A tool handle having a tang-receiving socket in one end thereof and provided in its peripheral surface adjacent said end with a longitudinal recess and a cavity at the inner end of said recess, the handle being formed with a circumscribing shoulder and with a socket at the shoulder and extending inwardly therefrom at an acute angle to the plane of the shoulder and at an acute angle to the axis of the handle, and a ferrule c011- sisting of a single length of wire having one endportion seated in said longitudinal recess and its. extremity embedded in the cavity at the inner end of said recess, the wire being bent at an abrupt angle to said end portion and then wrapped closely around the handle and over said end portion, the opposite end portion of the wire being driven into the socket opening at the said shoulder. 2A tool handle having a tang-receiving socket in one end thereof and provided in its Copies of this patent may be obtained for peripheral surface adjacent said end with a longitudinal recess and a cavityat the inner end of said recess, the handle beingformed with a circumscribing shoulder and with a.

cavity atthe inner end of said recess, the

wire being bent at anabrupt angle to said end portion and then wrapped closely around the handleand over saidend portion, the opposite end portion of the wire being driven into the socketopening at the said shoulder, and means adjacent the opposite end portions Of the wire to secure the adjacent coils thereof together and-retain the said end portions in their embedded relation to the handle. I j V V 8. A tool handle having a tang-receiving socket in one end and having radial notches formed in said end, and a ferrule consisting of a single length. of wire coiled closely around the end of the handle and having its opposite ends embedded in the handle, the radial plane of the handle in which the ends are embedded lying between the. radial planes of adjacent notches.

4. A tool handle having a tang-receiving socket in one end thereof andformed with a circumscribing shoulder back from the tangreceiving end, and "a wire ferrule consisting of a wire strand wrapped tightly-around the handle, the opposite ends of the wire strand being embedded in the handle and intermediate coils being unattached from one another, and the end portion of the wire next to the tang-receiving end of the handle being bent at an, abrupt angle and wrapped around the handle and over the portion embedded in the handle, the :two end coils at such end'coacting one to bind the embedded portion and the other, to serveas an abut: ment for the adjacent coil, and the shoulder to the handle serving asan abutment for another portion of the" ferrule. .7 j

In testimony whereof, I affiximy signature in presence of two witnesses.
